Detailed description of the related Art and all technical problems
Technical idea of total expansibility
Specifically, in order to solve the problems in the prior art, embodiments of the present application provide a method, an apparatus, a device, a storage medium, and a program product for deploying an intelligent contract. The following first describes a method for deploying an intelligent contract provided in an embodiment of the present application.
Fig. 1 is a flow chart illustrating a method for deploying an intelligent contract according to an embodiment of the present application. The method comprises the following steps:
s110, under the condition that a deployment request of the intelligent contract is received, generating a first identifier corresponding to the intelligent contract, wherein the first identifier is used for identifying the intelligent contract.
In this embodiment, the smart contract is a contract that uses blockchain technology and digital signatures to perform automated transactions, the contract being written by computer code and stored on the blockchain. The intelligent contracts need to be deployed in the blockchain first to provide the business operation functions based on the blockchain. The smart contracts may be deployed via a deployment request for the smart contracts.
When the block link receives a deployment request for the smart contract, the smart contract may be processed based on the deployment request.
In one embodiment, the contract processing is to perform data analysis of the deployment request, generate a unique first identifier for the intelligent contract to be deployed currently after the analysis, and store the first identifier in a contract register, where the contract register is used to store the identifier of the intelligent contract, and the contract register is stored in the blockchain gateway system.
In addition, after the intelligent contract is processed, whether the deployment parameters of the intelligent contract are complete or not needs to be checked, and whether the chain account responsible for checking the deployment parameters has corresponding rights or not needs to be checked, for example, whether the chain account under a certain tenant has the rights of deploying the contract or not needs to be checked. Only if these checks are passed, the next step is to split the smart contract.
S120, splitting the intelligent contract into a first sub-contract, a second sub-contract, a third sub-contract and a fourth sub-contract;
the method comprises the steps that under the condition that a transaction request aiming at the intelligent contract is received, the first sub-contract is used for determining the service type of the transaction request aiming at the intelligent contract, the transaction request is forwarded to a second sub-contract corresponding to the service type according to the service type, the second sub-contract is used for calling the third sub-contract to verify the transaction right of the transaction request, and under the condition that the transaction right verification is passed, the fourth sub-contract is called to execute the transaction request.
In this embodiment, after receiving the deployment request of the smart contract, the smart contract may be further split into a plurality of sub-contracts, each of which is responsible for implementing a portion of the functions of the smart contract. In this way, a large complex smart contract can be split into multiple independent modules for writing and managing. It aims to make the code of the contract easier to read and maintain, and at the same time, to improve the reusability and testability of the code.
In this embodiment, the smart contracts may be split into four types of contracts, namely a first sub-contract, a second sub-contract, a third sub-contract, and a fourth sub-contract. As an alternative embodiment, the first sub-contract may be a business contract for processing transaction logic; the third sub-contract may be a rights contract for managing and maintaining account information of the user; the fourth subcontract may be a billing transfer contract for performing specific transfer transaction logic; the second sub-contract may then be a smart contract for grouping other sub-contracts in the smart contract together to implement the functionality of the entire exchange. The sub contracts are divided into work and cooperate to jointly complete the functions of the intelligent contracts.
Based on the above embodiment, as shown in fig. 2, when the blockchain gateway system receives a transaction request for the intelligent contract, the blockchain gateway system first performs a basic rule check on the transaction request to check whether the transaction request is a request completely unrelated to the intelligent contract, isolates the unrelated request, and prevents the system from being maliciously attacked by the unrelated request. And after determining that the transaction request is a request with association, simultaneously performing flow control, and if the flow of the current system exceeds a threshold value, temporarily placing the transaction request so as to avoid a large number of request inrush in a short time to cause business system breakdown. Only if the basic rule check and the flow control are passed can the transaction request be forwarded to the business contract.
The business contract performs transaction request parameter verification, then forwards the transaction request to the corresponding intelligent contract according to the business type and the attribution business, the intelligent contract needs to call the authority contract to perform contract execution authority verification, and under the condition that the verification is passed, a specific charging transfer contract interface is called singly or in combination with the transaction request, the specific charging transfer contract executes the specific business transaction request, and then the transaction execution result is fed back to the intelligent contract. The intelligent contract feeds back the final contract execution result to the blockchain gateway system, and the gateway system feeds back to the user.
S130, generating a first sub-identifier for identifying the first sub-contract, a second sub-identifier for identifying the second sub-contract, a third sub-identifier for identifying the third sub-contract and a fourth sub-identifier for identifying the fourth sub-contract.
In this embodiment, after the smart contracts are split into the first sub-contract, the second sub-contract, the third sub-contract and the fourth sub-contract, in order to enable the sub-contracts to be quickly and accurately identified and invoked, it is further required to generate unique identification data for each sub-contract, and then bind the identification data and the sub-contracts one to one, that is, a first sub-identifier for identifying the first sub-contract, a second sub-identifier for identifying the second sub-contract, a third sub-identifier for identifying the third sub-contract and a fourth sub-identifier for identifying the fourth sub-contract.
S140, deploying the first sub-contract, the second sub-contract, the third sub-contract and the fourth sub-contract on a blockchain, and associating the first sub-identifier, the second sub-identifier, the third sub-identifier and the fourth sub-identifier with the first identifier.
In this embodiment, after the smart contract is split, the split first sub-contract, second sub-contract, third sub-contract and fourth sub-contract may be deployed onto the blockchain, and in addition, the first sub-identifier, second sub-identifier, third sub-identifier and fourth sub-identifier of the sub-contract need to be associated with the first identifier of the smart contract.
By establishing the association relationship, the sub-contracts can be managed and identified conveniently and efficiently, and the security of the sub-contracts can be improved by the binding operation because the sub-contracts must be verified and authorized by the intelligent contracts when the sub-contract operation is performed.
According to the method and the system, the complex intelligent contract is split into the plurality of sub-contracts, each sub-contract is only responsible for realizing a part of functions of the intelligent contract, a unique sub-identifier is generated for each sub-contract, and then the sub-identifiers are associated with the first identifier of the intelligent contract, so that the coupling property of the intelligent contract can be reduced, if a main contract wants to execute a part of functions, the sub-contract corresponding to the functions can be called, logic is clear in the process of realizing business transaction, the problem of redundant calling is avoided, and the execution efficiency of the intelligent contract is improved.
As an alternative embodiment, the generating a first sub-identifier for identifying the first sub-contract, a second sub-identifier for identifying the second sub-contract, a third sub-identifier for identifying the third sub-contract, and a fourth sub-identifier for identifying the fourth sub-contract includes:
determining a contract type, a contract name and contract data of the intelligent contract;
generating a first undetermined identification of the first sub-contract according to the contract type;
judging whether the same mark as the first undetermined mark exists or not;
determining the first to-be-identified as the first sub-identification in the absence of the same identification as the first to-be-identified;
and generating the second sub-identifier according to the contract name, and generating a third sub-identifier and a fourth sub-identifier according to the contract data.
In this embodiment, in order to guarantee the uniqueness of the identity of each sub-contract, the sub-identity of each type of sub-contract may be generated according to the related attribute of the smart contract, and after the sub-identity is generated, it may be checked whether the sub-identity is repeated.
As an alternative embodiment, the first sub-contract may be a business contract, the second sub-contract may be an intelligent contract, the third sub-contract may be a rights contract, and the fourth sub-contract may be a charge transfer contract. These sub-contracts may be deployed on three levels, namely, a proxy layer, a logical layer, and a data layer, with a first sub-contract deployed on the proxy layer, a second sub-contract deployed on the logical layer, and a third sub-contract and a fourth sub-contract deployed on the data layer.
Then, as shown in fig. 3, a first undetermined identifier of a first sub-contract on the proxy layer may be generated first according to the contract type of the intelligent contract, and since the first sub-contract is deployed on the proxy layer, the first undetermined identifier is a proxy layer contract identifier, and it is determined whether the same identifier as the proxy layer contract identifier exists in the proxy layer contract identifier library, if so, the first undetermined identifier is regenerated, and the steps are repeated, if not, the first undetermined identifier is directly determined as the first sub-identifier, and the first sub-identifier and the first sub-contract are bound.
Similarly, a second undetermined identifier of a second sub-contract on the proxy layer can be generated according to the contract name of the intelligent contract, and the second undetermined identifier is a logic layer contract identifier because the second sub-contract is deployed on the logic layer, and whether the identifier same as the second undetermined identifier exists in a logic layer contract identifier library or not is judged, if so, the second undetermined identifier is regenerated, the steps are repeated, if not, the second undetermined identifier is directly determined to be the second sub-identifier, and the second sub-identifier and the second sub-contract are bound.
Then a third undetermined mark and a fourth undetermined mark on the proxy layer can be generated according to the contract data of the intelligent contract, and the third undetermined mark and the fourth undetermined mark are deployed on the data layer, so that the third undetermined mark and the fourth undetermined mark are the contract marks of the data layer, whether the marks which are the same as the third undetermined mark and the fourth undetermined mark exist in a contract mark library of the data layer is judged, if the marks which are the same as the third undetermined mark and the fourth undetermined mark exist, the third undetermined mark and the fourth undetermined mark are regenerated, the steps are repeated, if the marks which are not exist, the third undetermined mark is directly determined to be a third undetermined mark, and the third undetermined mark and the third undetermined contract are bound; and determining the fourth undetermined identifier as a fourth sub-identifier, and binding the fourth sub-identifier and the fourth sub-contract.
Therefore, the uniqueness of the sub-identifier corresponding to each sub-contract can be ensured, and each sub-contract can be conveniently, accurately and quickly managed and identified.
As an alternative embodiment, after said associating said first sub-identifier, said second sub-identifier, said third sub-identifier and said fourth sub-identifier with said first identifier, said method further comprises:
determining a first sub-identifier corresponding to a transaction request for the intelligent contract under the condition that the transaction request is received;
acquiring the first sub-contract and a first association relation of the first sub-contract according to the first sub-identifier, wherein the first association relation is the association relation of the first sub-contract and the second sub-contract;
determining a second sub-identifier corresponding to the transaction request according to the first sub-contract and the first association relation;
acquiring the second sub-contract and a second association relation of the second sub-contract according to the second sub-identifier, wherein the second association relation is the association relation of the second sub-contract, a third sub-contract and a fourth sub-contract;
acquiring the third sub-contract and the fourth sub-contract according to the second sub-contract and the second association relation;
And merging the first sub-contract, the second sub-contract, the third sub-contract and the fourth sub-contract into a contract combination, and executing the contract combination according to the hierarchical relationship of the contract combination.
In this embodiment, after the smart contract is split into a plurality of sub-contracts, and the sub-contracts are deployed separately, each sub-contract is responsible for implementing a part of the functions of the smart contract, and the sub-contracts cooperate with each other, that is, the functions of the smart contract can be completed.
Specifically, as shown in fig. 4, the first sub-contract may be a business contract, the second sub-contract may be an intelligent contract, the third sub-contract may be a rights contract, and the fourth sub-contract may be a charge transfer contract. These sub-contracts may be deployed on three levels, namely, a proxy layer, a logical layer, and a data layer, with a first sub-contract deployed on the proxy layer, a second sub-contract deployed on the logical layer, and a third sub-contract and a fourth sub-contract deployed on the data layer. The contract identification of each agent layer is associated with the contract identification of at least one logical layer, which in turn is associated with the contract identification of at least one data layer.
As shown in fig. 5, in the case of receiving a transaction request for an intelligent contract, the transaction request may be parsed to obtain a first sub-identifier of a first sub-contract of an agent layer, and a relationship between the agent layer and a logic layer is obtained through the first sub-identifier, and a first association relationship between the first sub-contract and a second sub-contract is determined through the relationship between the agent layer and the logic layer; according to the first association relation, the second sub-identifier can be obtained through calculation, the relation of the logic layer and the data layer is determined, the second sub-contract and the second association relation are determined through the relation of the logic layer and the data layer, and similarly, the third sub-identifier and the fourth sub-identifier can be obtained based on the second association relation, and the third sub-contract and the fourth sub-contract are determined based on the third sub-identifier and the fourth sub-identifier.
Because the first sub-contract, the second sub-contract, the third sub-contract and the fourth sub-contract are matched with each other to complete the function of the intelligent contract, the sub-contracts on each level can be combined into a contract combination based on the sub-identification of each sub-contract, and then the contract combination is executed to complete the transaction request of the intelligent contract.
As an alternative embodiment, after said associating said first sub-identity, said second sub-identity, said third sub-identity and said fourth sub-identity with said first identity, said method comprises:
determining a second identification of any target contract in the case that the smart contract is incorporated into the target contract;
releasing the association relation of the first sub-identifier, the second sub-identifier, the third sub-identifier and the fourth sub-identifier with the first identifier;
the first sub-identity, the second sub-identity, the third sub-identity and the fourth sub-identity are associated to the second identity.
In this embodiment, after the smart contracts are split and deployed, the smart contracts may be combined with other contracts, in which case the sub-identities of the sub-contracts need to be adjusted to accommodate changes in the contract content.
Specifically, if the smart contract incorporates the target contract, it is necessary to release the association relationship of the first sub-identifier, the second sub-identifier, the third sub-identifier, and the fourth sub-identifier with respect to the first identifier, and re-associate the first sub-identifier, the second sub-identifier, the third sub-identifier, and the fourth sub-identifier to the second identifier of the target contract, and then delete the first identifier of the smart contract in the contract register.
In this way, the identifier of the sub-contract can be matched with the structure of the intelligent contract, so that each sub-contract can be managed and maintained more conveniently.
As an alternative embodiment, after said associating said first sub-identity, said second sub-identity, said third sub-identity and said fourth sub-identity with said first identity, said method comprises:
determining a target subcontracting related to the changed contract content in the condition that the contract content of the intelligent contract is changed, wherein the target subcontracting is one or more of the first subcontracting, the second subcontracting, the third subcontracting and the fourth subcontracting;
modifying the content of a target subcontext or the association relation of target subcontext, wherein the target subcontext is used for identifying the target subcontext.
In this embodiment, after the splitting and deployment of the smart contracts are completed, the contract contents of the smart contracts may change, and based on these changes, each sub-contract, or the sub-identifier of each sub-contract, needs to be adjusted to adapt to the change of the contract contents.
For example, the first sub-contract may be a business contract, the second sub-contract may be an intelligent contract, the third sub-contract may be a rights contract, and the fourth sub-contract may be a charge transfer contract.
If the business type of the intelligent contract is divided or the parameters of the execution request are changed, the content of the business contract can be correspondingly modified.
If the combination logic of the business in the intelligent contract changes, the association relation of the second sub-identifier of the intelligent contract can be correspondingly modified: the new identifier may be bound to the second sub-identifier, or the association relationship between the second sub-identifier and the existing identifier may be released. For example, a business transaction originally requires 3 specific charging transfer contract combinations to be completed, and now because of business requirements, another specific charging transfer contract needs to be added, an intelligent contract needs to be modified, and the call interface information of the newly added charging transfer contract is added to the intelligent contract, namely, the sub-identifier of the newly added charging transfer contract is bound with the second sub-identifier of the intelligent contract.
If the execution rights in the smart contract change, the contents of the master rights contract may be correspondingly modified. For example, if the current smart contract originally only needs to be executed by the link account a, and the newly added link account B now also has the contract execution authority, the authority contract needs to be changed, and the execution authority of the link account B is increased.
As an optional embodiment, said associating said first sub-identifier, said second sub-identifier, said third sub-identifier and said fourth sub-identifier with said first identifier comprises:
binding the first sub-identifier with the first identifier;
binding the second sub-identifier with the first sub-identifier;
binding the third sub-identifier and the fourth sub-identifier with the second sub-identifier.
In this embodiment, the sub-identifier of each sub-contract is associated with the first identifier of the smart contract, and instead of directly binding all the sub-identifiers with the first identifier, the sub-identifier corresponding to each sub-contract is directly or indirectly bound with the first identifier based on the function of each sub-contract.
For example, the first sub-contract may be a business contract, the second sub-contract may be an intelligent contract, the third sub-contract may be a rights contract, and the fourth sub-contract may be a charge transfer contract. The first sub-identifier and the first identifier of the business contract can be bound, the second sub-identifier and the first sub-identifier are bound, and the third sub-identifier and the fourth sub-identifier and the second sub-identifier are bound, so that the first identifier and each sub-identifier of the intelligent contract form at least one chain structure, and the relation among the contracts can be clearly determined through the chain structure.
